Fatshark Module Test Results: Trial 1
🕑 Added 2017-06-23 19:57:17 +0000 UTC Here are the results from the first round of testing. This test is the "out-and-back" test, where I fly in a straight line down the road as far out as I can go. This test does not involve diversity at all, since the modules should stay on the directional antenna the whole time. The goal is to simply test the raw range of the module.IMPORTANT NOTE: The AttitudeV4 was using a Triumph antenna, whereas the diversity modules were using both a Triumph and a 10 dBi X-air crosshair. This puts the AttitudeV4 at a huge disadvantage, but I thought it was fair for two reasons. First, Attitude doesn't do diversity, so it is most likely that people will simply fly it with an omni. Yes, you could put a patch on it instead of an omni and only fly in front of yourself, but most people won't do that. Second, Fatshark has done some marketing where they argue that diversity is kind of a waste of time and the FS module is nearly as good or just as good as a diversity setup with a patch antenna. So let's put that to the test.
Nevertheless, I must make very clear that this test is NOT FAIR AT ALL to the AttitudeV4 with OLED module.
Second, the ClearView is also using two omni antennas. This puts it at a disadvantage in this test, but ClearView is so damn good that I don't mind giving it a handicap. In this case, we can see that the ClearView did not fully overcome its handicap, but hey, them's the breaks.
HERE IS HOW THE SCORE WAS CALCULATED. I went through the video one second at a time. In each 1-second frame, I made a simple yes/no decision: is this image flyable? If the image was NOT FLYABLE, I awarded 1 point to the module. In other words, a lower score is better.
It's interesting to me that, in this test, the ClearView did not do as well as the directional antennas, while in previous tests, it did nearly as well. One difference is that I was using the Lumenier 8 dBi patch, and now I am using 10 dBi crosshairs. Hard to imagine that 2 dBi made such a difference though. Maybe the fact that the previous test was done in winter also mattered? I think all modules seemed to do worse than before.

Im using skyzone - love it, i only have to implement fs bracket with fan to it for hot days, but weather is really good thus year so im not rushing to it
Hey Josh. By 1-second-frame do you mean that you gave 1 point for each full second of all ~30 frames being unusable? Or jumped every 1 second of the timeline and checked the quality of the video feed every ~30 frames?
I find my Atty V4's better than my LaForge

This is a single run.

It's the Commander goggles.
Multiple passes? Averages? Or just one pass through each test? I presume you've cleared out any aberrant environmental factors... seems like you live in a rural location, so that's nice. Just mulling over your results. Thanks for this!

Is the Commander listing the Aomway Commander goggles or is there a Fatshark module I'm not aware of? I have a set of Aomway Commanders on the way and am very happy to see how they faired if that is the case.
